Explanation:
it holds protons and neutrons together
Strong nuclear force holds protons and neutrons together.
What is protons?Proton is a subatomic particle with a positive electric charge.
What is neutrons?Neutrons is a subatomic particle of about the same mass as a proton but without an electric charge.
What is nuclear force?The nuclear force is a force that acts between the protons and neutrons of atoms.
What is strong nuclear force?The strong nuclear force is created between nucleons by the exchange of particles called mesons. It is stronger than the force of gravity as it binds the fundamental particles to form large particle.
Strong nuclear force is strongest force in nature. So, it is much stronger than gravitational forces. It binds the neutral charges i.e. neutron instead of repelling them. It is a short range force so it can not act over very large distances.

What is the speed of light?The speed of light, also known as the velocity of light, is a fundamental constant of nature and is one of the most well-known physical quantities. It is defined as the speed at which electromagnetic radiation (light) travels through a vacuum, which has a constant value of 299,792,458 meters per second (m/s).
This speed is considered to be the fastest that anything can travel in the universe, and it is a critical component in many physical and biological processes. The speed of light is used in a wide range of scientific and technological fields, including optics, electronics, astronomy, and quantum mechanics. It is considered to be a universal constant and does not change with time, distance, or the medium through which it travels.

for every 1000 joules or useful energy output, the heater wastes 100 joules, find the input energy of the heater.
Answer:
the Input Energy is 1,100 J
Explanation:
Given;
useful energy, = 1000 J
energy wasted, = 100 J
The total or input energy is given as;
Input Energy = useful energy + energy wasted
Input Energy = 1000 J + 100 J
Input Energy = 1,100 J
Therefore, the Input Energy is 1,100 J

An object moves through space with balanced forces acting on it. Which statement
best describes the speed and direction of the object as long as the forces acting on it
remain balanced?
A. The speed and direction of the object will both change.
B. The speed and direction of the object will remain constanti
C. The speed will change, but the direction will remain constant.
D. The speed will remain constant but the direction will change
Answer:
B
Explanation:
Newton's first law of motion states that every object will continue in a state of rest or uniform motion in a straight line unless a resultant force acts on it
balanced force means resultant force is 0N
this means that the speed will not change as it uniform and the direction will not change because it will continue at the same speed in a statight line and direction

Time ____ is a phenomenon in which objects in motion and objects at rest experience time differently.
Time dilation is a phenomenon in which objects in motion and objects at rest experience time differently.
What is Time?This can be defined as a measurable period during which an action exists or continues and the standard unit is seconds.
Time dilation occurs when objects in motion and objects at rest experience time differently. In this situation, the clock of an individual tends to be slower than that of the other and is known as a theory of relativity.

A boy is pulling his two sisters on a sled.
If one sister weigh 30.0 kg, the other
weights 40.0 kg, and the coefficient of
kinetic friction is 0.120, how much force
is required to pull the sled?
[?] N
Answer:
Explanation:
The oly way we can figure this out is if the boy is pulling the sled at a constant velocity. If not, we need a value for acceleration, and you don't have that here. If the boy is pulling the sled at a constant velocity, then the value for acceleration is 0, making this a really simple problem. I'm going with that, since there is no way to answer you otherwise. If velocity is not constant, please either repost the question or put it in the notes section under the question as it stands. If acceleration is 0, then
F - f = ma becomes
F - f = m(0) which is
F - f = 0 and
F = f which says that the applied force is the same as the frictional force. We need then to find the frictional force, which has an equation of
f = μ[tex]F_n[/tex] where normal force is the same as the weight of the 2 girls. We will find that, then:
Each girl's mass is different so the normal force/weight equation is
w = (30.0)(9.8) + (40.0)(9.8) to get
w = 290 + 390 and
w = 680. Plug that into the frictional force equation:
f = (.120)(680) so
f = 82N

A roller coaster goes down a slope with a starting speed of 5 m/s then 6
seconds later at the bottom of the slope the roller coaster is moving at a
speed of 27 m/s. What is the acceleration of the roller coaster? **Round to
1 decimal place**
Answer:
Acceleration = 3.67 m/s²
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
Given the following data;
Initial velocity, u = 5 m/s
Final velocity, v = 27
Time, t = 6
To find the acceleration;
Acceleration = (v - u)/t
Acceleration = (27 - 5)/6
Acceleration = 22/6
Acceleration = 3.67 m/s²

The graph shows the layers of Earth's atmosphere. Which statement best describes the relationship between temperature and altitude in the atmosphere?
A. The relationship between temperature and altitude is variable and unpredictable.
B. Overall, the temperature of the atmosphere increases with altitude.
C. The relationship between temperature and altitude is different in each zone of the atmosphere.
D. Temperature decreases with altitude until the stratosphere is reached, and then it increases from there.
Answer:
The best statement which describe this is actually:
D. Temperature decreases with altitude until the stratosphere is reached, and then it increases from there.
Explanation:
From the graph shown, it could be seen that, temperature decrease with height. The higher the height, the lower the temperature. For example, from the graph, when the height was around 50 km, the temperature was within the range of -10⁰C to 0⁰C. On the other hand, when the height increases around 78 km, the temperature decreases to the range of to -70 ⁰C to -80⁰C
Can someone help me out?
Answer:
1) The car is slowing down
2) A = 40N forward & B = 25N up
Explanation:
Whenever you're dealing with forces on moving objects, it is important to look at each of the numbers and the directions they're going in.
With the racecar, we see it has four forces on it, 2,000 N up and down, 8,000 back, and 6,000 N forward. Now, each of these forces are going in their respective directions, but they are most in comparison with the force going in the opposite direction (vertical axis, horizontal axis). The two 2,000 N forces will cancel each other out since there is an equal force in both directions, causing a net force of 0 N on the vertical axis. This is because the car is most likely moving on a flat surface. As for the horizontal axis, we simply subtract 6,000 & 8,000 to get a net force of -2,000 N in the backwards direction, telling us that the car is slowing down.
As for the boxes, we see the same vertical and horizontal axes, but separated to each box. Box A has a net force of 40 N in the forward direction and Box B has a net force of 25 N in the upward direction.

a snail is at rest. it accelerates at a rate of 0.0075m/s^2. calculate the time it takes to reach a speed of 0.0135m/s
Answer:
1.8 secondsExplanation:
Initial velocity (u) = 0 m/s[Since, it is at rest. ]
Acceleration (a) = 0.0075 m/s²Final velocity (v) = 0.0135 m/s²We are asked to calculate time taken to reach a speed of 0.0135m/s.
By using the first equation of motion,
→ v = u + atv denotes final velocityu denotes initial velocitya denotes accelerationt denotes time takenSubstituting values,
→ 0.0135 = 0 + 0.0075t
→ 0.0135 = 0.0075t
→ 0.0135 ÷ 0.0075 = t
→ 1350000 ÷ 750000 = t
→ 135 ÷ 75 = t
→ 1.8 = t
→ Time taken = 1.8 secondsTherefore, it takes 1.8 seconds to reach a speed of 0.0135m/s.
